RESUMEN
INTRODUCTION: A major episode of hepatic cytolysis, rapidly regressive and occasionally recurrent, evokes a bilary or toxic pathology. We report an exceptional case in which several episodes of cytolysis were secondary to a paroxystic cardiac rhythm disorder. OBSERVATION: A 44 year-old woman was hospitalized 3 times during 4 months for episodes of asthenia and rapidly regressive cytolysis. Lithiasic, viral, metabolic, autoimmune and toxic causes were eliminated. A cardiac rhythm disorder was revealed during the last two episodes and diagnosis was made of intermittent and asymptomatic ventricular tachycardia, secondary to arryhthmogenic right ventricular dysplasia, and was confirmed on the electrocardiogram, cardiac scan and magnetic resonance imaging. Treatment of the cardiac rhythm led to the absence of further relapse. COMMENTS: In our patient, the clinical and chronological imputability appeared highly probable. The responsibility of perturbed cardiac rhythm in the genesis of an ischemic hepatopathy is classical, but little documented. Our observation confirms that severe unexplained cytolysis requires systematic search for a cardiac rhythm disorder, even in the absence of a known or symptomatic cardiopathy.

PURPOSE: A relationship between vasomotor tone changes in mesenteric and renal vessels in cirrhotic patients has been suspected but remains controversial. The aim of this study was to assess by duplex Doppler sonography the changes in the circulatory resistance of the renal arteries and superior mesenteric artery (SMA) following meal-induced splanchnic vasodilatation. METHODS: Twenty-seven cirrhotic patients and 15 healthy volunteers with no hepatic or renal dysfunction were prospectively included in the study. The resistance index (RI) of the SMA and of the right and left renal arteries was measured by duplex Doppler sonography before and 30 minutes after ingestion of a standard 400-kcal balanced liquid meal. Values in controls and patients and values before and after the meal were compared, and correlations between RIs, Child-Pugh class (liver function), and creatinine clearance were assessed in cirrhotic patients. RESULTS: The fasting renal artery RI was greater in cirrhotic patients than in controls (p < 0.0001), but there was no difference in fasting SMA RIs. After the meal, there was a significant decrease in the SMA RI in controls (0.85 +/- 0.04 before versus 0.74 +/- 0.03 after meal, p = 0.0001) and in cirrhotic patients (0.85 +/- 0.04 before versus 0.77 +/- 0.04 after, p = 0.0001) and a significant increase in the renal artery RI (0.57 +/- 0.06 before versus 0.62 +/- 0.05 after in controls, p = 0.001; 0.68 +/- 0.07 before versus 0.70 +/- 0.07 after in cirrhotic patients, p = 0.001). No correlation was found in cirrhotic patients between the changes in renal artery RI and the postprandial SMA RI decrease, the Child-Pugh class, or the creatinine clearance. CONCLUSIONS: Meal-induced SMA vasodilatation (RI decrease) is associated with a marked increase in the renal artery RI, worsening the renal vasoconstriction in cirrhotic patients.

INTRODUCTION: Collagenous gastroenterocolitis is a recently known rare cause of chronic diarrhoea, that raises numerous nosological and diagnostic problems. OBSERVATION: A 41 year-old woman was hospitalised for severe diarrhoea, diagnosed as collagenous gastroenterocolitis. Gastroscopy and ileocolonoscopy were macroscopically normal, but a 20 to 40 microns thick sub-epithelial collagenous band was revealed in the gastric, duodenal and colic biopsies. Parenteral nutrition and treatment with salazopyrine and prednisolone progressively normalised the transit. Three months later, only a 30 microns colic mucosa collagenous band persisted. All the biopsies taken during control gastro-colonoscopy 2 years later were histologically normal. After 5 years follow-up and absence of treatment, the patient no longer presented diarrhoea or biological abnormality. COMMENTS: This exceptional observation is a reminder that sub-epithelial collagen deposits are not always limited to the colon and therefore justify, in patients with collagenous colitis, systematic gastro-duodenal and ileum biopsies.

Antiphospholipid antibodies (aPL) have been detected in various liver diseases, particularly cirrhosis. The role of alcoholic consumption per se has been suggested. The aim of our study was to assess the prevalence of aPL in patients with alcoholic liver disease at various states and to correlate the presence of aPL with both liver injury and alcoholic consumption. Three groups were prospectively included. Group A: 74 controls (age- and sex-matched); group B: 46 patients with alcoholic steatosis; group C: 28 patients with alcoholic cirrhosis. For each patient, lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I antibodies were tested. The prevalence of aPL (presence of at least one positive test) was 5% in group A, 20% in group B and 50% in group C (P < 0.04). No correlation appeared between aPL and Child Pugh score in group C. No correlation was found between the presence of aPL and alcohol intake in patients with either steatosis or cirrhosis. Our study confirms that aPL positivity is more frequently encountered in patients with alcoholic liver disease than in controls. Their prevalence increases with the degree of histological damage but not with the level of alcoholic intake.

BACKGROUND: Liver iron deposits are frequent in viral C cirrhotic patients but their role is not well defined. AIMS: To investigate the effect of liver iron excess on the prevalence of hepatocellular carcinoma (HCC) in patients with viral C cirrhosis. METHODS: Hepatic iron was evaluated retrospectively using a semiquantitative method in liver biopsies of 104 viral C cirrhotic patients, 48 with HCC and 56 controls (HCC free). Corrected total iron score (0-60) was defined by the sum of three scores: hepatocytic iron score (0-36), sinusoidal iron score (0-12), and portal iron score (0-12), multiplied by 3/3, 2/3, or 1/3 according to the heterogeneous iron localisation in the nodules. RESULTS: After adjustment for known risk factors for HCC, regression analysis showed that iron deposits (corrected total iron score >0) were more frequent in HCC patients than in controls (odds ratio 4.94; 95% confidence interval 1.59-15. 32; p=0.0056). The median of corrected total iron score was significantly higher in HCC patients than in controls (odds ratio 1. 092; 95% confidence interval 1.01-1.13; p=0.021). This liver iron overload was sinusoidal (odds ratio 5.2; 95% confidence interval 1. 82-15.11; p=0.0022). CONCLUSIONS: Liver iron deposition was more frequent and more important in viral C cirrhotic patients with HCC than in HCC free controls. Liver iron overload seems to contribute to the development of HCC in patients with viral C cirrhosis.

BACKGROUND/AIMS: Bacterial infections, specially Staphylococcus aureus (S. aureus) septicemia, remain a leading cause of death following liver transplantation. It has been demonstrated that nasal carriage of S. aureus is associated with invasive infections in patients undergoing hemodialysis and could be decreased by use of antibiotic nasal ointment. However, in cirrhotic patients, the frequency of nasal carriage is unknown. The aims of this study were to determine the prevalence of S. aureus nasal carriage in cirrhotic patients and to assess nosocomial contamination. METHODS: One hundred and four patients were included in a prospective study, 52 cirrhotic and 52 control (hospitalized patients without cirrhosis or disease which might increase the rate of nasal carriage of S. aureus). On admission and after a few days of hospitalization, nasal specimens from each anterior naris were obtained for culture. S. aureus was identified by the gram strain, positive catalase and coagulase reactions; antibiotic susceptibility was determined using a disk-diffusion test. RESULTS: Both groups were similar with regard to age and sex. The prevalence of nasal colonization on hospital admission was 56% in cirrhotic patients and 13% in control patients (p = 0.001). After an average of 4 days, 42% of cirrhotics and 8% of control patients were colonized (p = 0.001), without any nosocomial contamination. Three strains out of 29 were oxacillin-resistant in cirrhotic patients, and none in controls (p>0.05). There was no statistical difference in carriage rate according to sex, age, cause of cirrhosis and Child-Pugh score. Previous hospitalization (OR, 6.3; 95% CI, 2.3 to 19.9; p = 0.0006) and cirrhosis (OR, 4.4; 95% CI, 1.5 to 13.4; p = 0.0048) were independent predictors of colonization. CONCLUSION: Cirrhotic patients had a higher S. aureus nasal carriage rate than control subjects. Previous hospitalization and cirrhosis diagnosis were correlated to nasal colonization. Further studies are necessary to determine if nasal decontamination could reduce S. aureus infections after liver transplantation.

Pulmonary involvement is very rare in giant cell arteritis. The sign that is most often encountered seems to be dry cough which can remain, for a long time, the sole manifestation of this disease. We report a case of giant cell arteritis in a 66 year old woman that expressed for only symptom a dry cough during one year. A rapid regression of clinical symptoms and radiologic signs have been observed with steroid therapy. Presence of isolated cough along with biological marks of inflammation in a elderly patient should lead to temporal biopsy when no other evidence cause has been found.
